Stratigraphic Modeling & Fault Analysis

Fault Contact Editing

  • Seismic horizons need to be validated where picking is difficult, at the fault boundary. Fault displacement can be mapped on the fault plane to look at the consistency of the interpretation.
  • The horizon contacts can be edited to remove, for example, a displacement inversion or ill-shaped displacement map.

Fault Analysis

  • Once the displacement has been corrected, the quality of the fault as a seal can be looked at by computing a juxtaposition map.

Stratigraphic Modeling

  • The horizon contacts can be edited to remove, for example, a displacement inversion or ill-shaped displacement map.

Isochore Modeling

  • The presence of the module enables the computation of isochores in either the Structural Workflow or the Stratigraphic Workflow. Isochores are computed using well marker information, limited horizon interpretation between 2 major horizons, erosion boundaries and horizontal well information. The unique utilization in the industry of the horizontal well information ensures the right stratigraphic positioning of the fine layers.

Stratigraphic Modeling And Fault Analysis Facilities Include:

  • Quick tool to visualize and modify azimuth and dip
  • Fault displacement
  • Juxtaposition map
  • Creation of isochore surfaces
  • Fault/fault or horizon/fault contact tuning
  • Horizon crossing control
